FAQs Answers to the most common questions.
How do I tell a male Katherine’s Fairy Wrasse from a female or juvenile, and will the colors change after purchase?
Males develop the species’ showy terminal coloration: stronger pink-red/orange body tones, brighter blue/green facial highlights, and more extended fins, especially the dorsal and tail margins. Females and juveniles are usually smaller, plainer, and more tan, peach, or brownish with less pattern intensity. In a healthy tank, a female or juvenile can transition to male if no dominant male is present, but the change is gradual and depends on social conditions, diet, and overall stability. Newly purchased individuals may also look muted from stress, so expect the full coloration only after acclimation and consistent feeding.
What tank size and setup does Katherine’s Fairy Wrasse really need to stay healthy long-term?
A minimum of 75 gallons is the practical starting point, with 90+ gallons being much better if you want stable water quality and room for swimming. They are active, open-water wrasses that appreciate long horizontal space, a tight-fitting lid, and plenty of rockwork with caves and crevices for nighttime sleeping and retreating. A sand bed is helpful but not as essential as for sand-burying wrasses. Keep the aquascape secure, with sheltered zones and open lanes, because they can be skittish and may dash when startled.
Will Katherine’s Fairy Wrasse eat shrimp, snails, or other cleanup crew in a reef tank?
It is generally reef-safe and usually ignores corals, snails, and most cleanup crew. It may opportunistically pick at tiny ornamental crustaceans like very small shrimp, copepods, or amphipods, especially if they fit its mouth, but it is not typically a predator of larger cleaner shrimp or snails. Like many fairy wrasses, it is much more likely to hunt microfauna and frozen meaty foods than bother established reef invertebrates. Still, very small decorative shrimp and newly introduced tiny livestock should be watched.
What should I feed Katherine’s Fairy Wrasse to keep its color strong and prevent it from wasting away?
Feed a varied diet of small meaty foods multiple times per day if possible: enriched mysis, finely chopped seafood, quality marine pellets, frozen copepods, and other planktonic fare. This species does best with frequent feeding because it is an active forager with a relatively high metabolism. Color and body condition improve when the diet includes carotenoid-rich foods and regular vitamin enrichment. A tank with live rock and pod production is a big plus, but it should not be relied on as the only food source.
How aggressive is Katherine’s Fairy Wrasse, and can I keep more than one fairy wrasse together?
It is usually peaceful to semi-peaceful, but males can be assertive toward similar-looking fairy wrasses, especially other males in the same genus or closely related species. In larger tanks, it can often be kept with other wrasses if introduced carefully and if there is enough space and multiple hiding areas. The safest approach is to keep one male with females or with dissimilar tankmates, or to add fairy wrasses at the same time in a sufficiently large aquarium. Like many wrasses, it may become more territorial if underfed or cramped.

The female Purple Velvet Fairy Wrasse, Cirrhilabrus luteovittatus, is an elegant saltwater fish with more understated coloration than the dramatic terminal-phase male. Females and initial-phase individuals typically display warm orange-red to olive and purplish tones that become noticeably paler along the underside, often accompanied by fine reddish spotting across the upper body. As with other fairy wrasses, coloration can change significantly with maturity and social status, and a female may eventually transition into a male.
Native to the central-western Pacific, particularly the Marshall and Caroline Islands, this species inhabits lagoon patch reefs and coral-and-rubble environments where small groups swim above the reef feeding on zooplankton. Its manageable adult size, active swimming behavior, attractive coloration, and excellent compatibility with corals make the Purple Velvet Fairy Wrasse a desirable marine aquarium fish for established reef aquariums and peaceful fish-only systems.
Quick Care Guide

Scientific Name: Cirrhilabrus luteovittatus
Tank Requirements
The Purple Velvet Fairy Wrasse should be maintained in an established marine aquarium with ample open swimming room and substantial rockwork for security. Adults can reach approximately 4.5–5 inches, and a 55-gallon or larger aquarium provides suitable long-term space for this active species.
Arrange live rock to create caves, overhangs, and narrow crevices where the wrasse can retreat when frightened and rest at night. Unlike sand-burying wrasses, Cirrhilabrus species normally shelter within reef structure, so a deep sand bed is not required.
Moderate water movement, good oxygenation, efficient filtration, and stable water quality are ideal. Areas of subdued lighting or shaded rockwork are also beneficial and provide secure retreats.
A tightly fitted mesh or solid aquarium cover is essential. Fairy wrasses are accomplished jumpers and can escape through very small openings around plumbing, cables, and equipment.
Diet and Feeding
The Purple Velvet Fairy Wrasse is primarily a planktivore that naturally feeds on zooplankton suspended in the water column.
Offer a varied diet including mysis shrimp, enriched brine shrimp, copepods, finely chopped marine seafood, frozen plankton blends, and appropriately sized high-quality marine pellets. Small foods dispersed through the water column encourage natural feeding behavior.
Two to three smaller meals per day are preferable when practical. An established reef aquarium containing naturally occurring copepods and other microfauna can provide additional feeding opportunities between prepared meals.
Temperament and Tankmates
The female Purple Velvet Fairy Wrasse is generally peaceful toward unrelated marine fish and works well in a community-oriented reef aquarium. Suitable tankmates include clownfish, gobies, blennies, cardinalfish, anthias, peaceful tangs, flasher wrasses, and compatible fairy wrasses.
Territorial behavior can occur among members of the same species or closely related fairy wrasses, particularly as individuals mature. In larger aquariums, a male may be maintained with females when adequate swimming space and shelter are available.
Like other Cirrhilabrus species, this wrasse is a protogynous hermaphrodite. A female may transition into a male depending on the social structure of the aquarium.
Avoid highly aggressive tankmates that may continually intimidate the wrasse or prevent it from feeding comfortably.
Reef Compatibility
The Purple Velvet Fairy Wrasse is considered reef safe. It does not normally damage healthy corals and is generally compatible with ornamental shrimp, crabs, snails, clams, and other common reef invertebrates.
Its natural feeding behavior is focused primarily on tiny planktonic organisms suspended above the reef rather than larger benthic invertebrates. Naturally occurring copepods and other microcrustaceans may be consumed as part of normal feeding behavior.
Its combination of peaceful temperament and excellent coral compatibility makes it especially well suited to mixed and coral-dominated reef aquariums.
Water Parameters
Temperature: 75–80°F
Specific Gravity: 1.024–1.026
pH: 8.1–8.4
Alkalinity: 8–12 dKH
Stable conditions are more important than chasing exact numbers. Maintain consistent temperature and salinity along with good oxygenation, dependable filtration, and regular aquarium maintenance.
Common Considerations
-
Female coloration: Females are more subdued than mature males, typically showing orange-red, olive, or purplish coloration with a paler underside and fine body spotting.
-
Sex change possible: Females may transition into males depending on social conditions within the aquarium.
-
Exceptional jumping risk: A tightly fitted aquarium cover is essential, including around plumbing and equipment openings.
-
No deep sand bed required: This fairy wrasse normally sleeps and shelters within rockwork rather than burying itself in the substrate.
-
Frequent feeding preferred: Multiple smaller meals of planktonic and protein-rich marine foods help maintain healthy body condition.
